I wear makeup spontaneously. I don't really react to makeup very much - mostly because I don't wear foundation as a result of my skintone being fairly even. Most I ever have to do is a few spots of concealer and a bit of powder to even out the texture. The worst problem I ever have is with mascara; I get styes like crazy if I wear mascara. Now I paint my eyelashes with liquid eyeliner; comes off easier and less eye irritation, not to mention less spiderlash.
My boyfriend has rarely ever seen me in makeup (largely because I was in culinary at the time), and he's actually seen me in full-up Zombie Mode and still thought I was a pretty zombie.
